The role of chronotype in the interaction between the alerting and the executive control networks.

Although admittedly the interaction was only marginally significant, F (1, 16) = 4.111, p = 0.060, η 2 = 0.195 it is worth noting that the alerting tone reduced the differences between the optimal and non-optimal time of day by almost half (synchrony effect = 25 ms) in comparison to when the alerting tone was absent (synchrony effect = 44 ms).
